What a purpose of apcv valve and where the location in the engine?
The PCV (Positive Crankcase Ventilation) valve allows the engine to burn off the gases that build up in the crankcase and at the same time protect the flammable gases from igniting from a backfire.
What does a crankcase breather do?
The PCV or positive crankcase ventlation valve does as it is named. It will remove harmful gases from the engine. Also, you can find breather caps on the valve covers, this also helps to remove and fumes from the crankcase or engine base.
What Is Positive Crankcase Ventilation?
An engine's combustion chamber does not have a perfect seal. At the time of ignition, some of the expanding gas leaks past the rings into the bottom (crankcase) of the engine, known as the Blowby Gases. This gas contains oil and partially burned fuel that can pressurize the bottom half of the engine, leading to blown oil seals and making it harder for the engine to work.The Positive Crankcase Ventilation system allows a route for these gases to be scavenged and passed back through the engine for consumption. It reduces emissions and keeps the engine from over pressurizing.
How does fuel get into the oil on a td5 defender?
If you're getting gasoline in the oil, then you have bad piston rings that are allowing gases into the crankcase. You can find which piston(s) have bad rings by doing a compression test; a cylinder with bad rings will have lower compression.
What is a breather used for?
Allow pressurized gases to vent from the crankcase.
What system uses air flow around a tube to draw gases out of crankcase?
there are two answers to this question. one is the emission system. it burns spent gases the leak past the rings by essentially sucking them back to the top of the engine and re-entering the intake air stream. the other is the PCV system. that is the part of the emission system that allows the spent gases to re-enter the air stream while preventing a negative crankcase pressure which would be detrimental to the engine.
What does a PVC do and what does it stand for and where does it go in an engine?
Well, keep in mind I'm not a mechanic. I think you mean a PCV valve, not a PVC valve. PCV stands for Positive Crankcase Ventilation. A system using a PCV valve evacuates gases from an engine's crankcase, and I believe they always go on top of the crankcase. It's purpose is for fuel economy and the environment.

What does the PVC valve do?
The PCV valve is a control device which sends partially burned gases that come from the engine's crankcase to the combustion chamber. The PCV is generally used to regulate the air flow.
What sequence describes how a four-stroke engine cycle powers the engine?
Air and fuel intake, compression and ignition, combustion and expansion, exhaust
What cause crankcase back pressure in a four stroke outboard motor?
All four-stroke engines have crankcase back pressure because gases blow by the piston rings. They used to just drill a hole in the crankcase to let it out; when the government figured out this was a major source of pollution, they required the gases be captured and burned. To make this work, the hole is fitted with a one-way check valve and a hose. The hose is routed to the air intake on the carb or fuel injection. This is called "positive crankcase ventilation" (or "PCV") because the intake system's vacuum sucks the gases out of the crankcase. The valve is there for safety reasons: if the engine backfires through the carb, the PCV valve keeps your engine from exploding - which happened before the PCV system was invented. If you're getting back pressure, this system isn't working. And the problem's usually that the PCV valve is clogged or stuck shut. They should be replaced every year at the start of boating season, but since yours is clogged replace it now. If you pay $10 for one you went to a really expensive store.
How gases are liquified?
Usually by compression and then cooling the resulting concentrate.
Which state of matter is most resistance to compression?
gases :)
